In the ancient world there were three medicine kingdoms: animal, vegetable, and mineral. Following her previous acclaimed volumes on animal (The Illustrated Bestiary) and vegetable (The Illustrated Herbiary), Maia Toll fulfills the call for mineral with The Illustrated Crystallary, exploring the mystical qualities of 36 fascinating crystals and minerals, including amethyst, hematite, mica, smokey quartz, emerald, ruby, and more. Combining bits of ancient wisdom with her own insights, Toll illuminates the aspects and energy of each stone and, through rituals and reflections, the life guidance it might offer contemporary readers. Obsidian’s shiny surface and sharp edges reflect the shadowy corners of the self and serve as the tool for cutting them loose.
